151-0719-00L | Quality of Machine Tools - Dynamics and Metrology at Micro and Submicro Level | 4 credits | 2V + 1U | A. Günther, D. Spescha | |
Abstract | The course "Machine tool metrolgy" deals with the principal design of machine tools, their spindles and linear axes, with possible geometric, kinematic, thermal and dynamic errrors of machine tools and testing these errors, with the influence of errors on the workpiece (error budgeting), with testing of drives and numerical control, as well as with checking the machine tool capability. | ||||
Objective | Knowledge of - principal design of machine tools - errors of linear and rotational axes and of machine tools, - influence of errors on the workpiece (error budgeting) - dynamics of mechanical systems - measurement data acquisition / digital signal analysis - experimental modal analysis - geometric, kinematic, thermal, dynamic testing of machine tools - test uncertainty - machine tool capability | ||||
